YR 2013 FD 2013 PB F. A. Davis Company PP New York, NY SN 9780803629578 LK fadavispt.mhmedical.com/content.aspx?aid=1180746137 RD 2024/04/19 AB Imagine taking a measurement on a patient and not having an idea about the extent of measurement error associated with the measurement. Would you be confident that the measurement was really meaningful and would you use it for making important clinical decisions? For example, let's say that your patient was being treated for a head injury and you were interested in quantifying the extent of spasticity in the patient's upper extremities. Would you be comfortable using a spasticity measure that your colleague recommended but that you had never used or read about? Without having a good idea of how much error is associated with a measurement, we do not know how confident we can be in a measured value or the clinical decisions based on the measurement.
